KCl is soluble in DMF
Drying DMF (Dimethylformamide) involves using drying agents like molecular sieves or calcium hydride to remove any trace amounts of water. It can also be dried by distillation under reduced pressure to remove water content. The dried DMF should be stored under anhydrous conditions to prevent moisture absorption.

Yes, you can solve 0,04 g of NaCl in 100 g (105 ml) of DMF. From Wikipedia.

Yes, Dimethylformamide (DMF) is suitable for UV spectroscopy detection as it has a wide UV absorption range that allows for analysis in this spectral region. However, it is important to consider that DMF itself absorbs UV light, so baseline correction and appropriate blank subtraction are necessary for accurate measurements.
you can try distillation. benzene has a boiling point of 80 deg C and DMF is more like 150 deg C. i don't think it will form an azeotrope (may be wrong though). if it does form an azeotrope and the concentration of DMF is not too high, you can try washing the distillate in a sep funnel with water. DMF is freely miscible in water, whereas benzene is non-soluble in water.
Yes, dimethylformamide (DMF) is a volatile organic solvent. It has a relatively high boiling point of around 153°C and a low vapor pressure at room temperature, but it is still considered volatile compared to non-volatile solvents.
It may be the DMF has gone, mine did the same. The DMF is the dual mass flywheel, when its replaced the clutch has to be replaced as well, so its an expensive job (£1000+), luckily I had only just bought the car so the dealer paid under warranty. Best to take it to a VW place and get them to check...
I tried to dissolve AgNO3 in DMF and i found that it is easily soluble in it . So one can have a try, distilled water can also be best employed for the same .
Dual Mass Flywheel Pre-fitting Checks It is essential that you check the DMF/DFC (the procedure is the same for both) during every clutch replacement - if you fit a new clutch to a worn DMF/DFC, the flywheel will completely destroy it. If the clutch is making any unexplained noises, vibration or intermittent clutch slip it could be caused by a worn DMF. - Rattles and clonks during enginie start up or turn off. - Excessive gear rattle - Unusual noises - Driven plate damage - Driven strap damage Rotate the inner mass by hand anticlockwise and mark the flywheel then rotate it clockwise and measure the travel. REPLACE if the movement is: - Less than15mm or - More than 30mm Rock the inner mass from side to side. REPLACE if movement is: - More than 2mm for passenge - More than 4mm for light side to side
